I have an S3 OLED which I was just able to recover from a GSOD loop situation.
My shows were all there and it connected and fully downloaded the guide data.
However it doesn't show any shows as recording in the todo list and when I view upcoming episodes, nothing shows up.
I think this is due to tivo still running GC and Indexing on the large 2 week set of data it downloaded, but I am not sure. Possibly something I did to resolve the GSOD loop messed things up.
I always thought it did the GC/Indexing as the last step of the connect to the mothership (ie "Loading"), but the System Information page says
Guide View Cache:
Cache To: Thursday December 31 4:00 pm
Status: Running, since...
Wednesday September 11 12:05 pm
My other S3 OLED says "Idle, since..."
It is a little disconcerting right now because nothing shows up as recording in the todo list and nothing shows up under view upcoming episodes, even though there is guide data for 13 days. While I think this is all because the GC/Indexing isn't done yet, I'm not sure if that is just a red-herring and I messed something else up. Also even if just takes a while, I'm not sure if it'll get done before 8pm primetime hits and it needs to record stuff.
I've read about other units having trouble with indexing guide data forcing their owners to manually force the indexing. Hopefully that isn't the situation here.
